4.3.2. Forward Modeling¶
The program gzfor3d_60.exe performs the 3D forward modelling of gravity data for a density contrast model defined on a tensor mesh.
4.3.2.1. Running the Program¶
To run the executable, open a command window. In order, enter the path to the gzfor3d_60 executable, the tensor mesh file, the survey file, the density contrast model file and a topography file (optional). This in shown below.
4.3.2.2. Units¶
Data: gravity anomaly in mGal
Model: density contrast model in g/cc
4.3.2.3. Output Files¶
The program gzfor3d_60.exe creates the following output files:
gzfor3d.grv: Predicted data file.
gzfor3d.log: Log file which provides details about the parameters used in the forward modelling and diagnostic information about the results.
